FAQ

What is 10A antibacterial protection in maternity underwear?

10A is the highest grade of antibacterial protection in textile standards, indicating that the fabric inhibits bacterial growth by 99% or more. For maternity underwear, 10A antibacterial protection is especially important because pregnancy hormonal changes can increase sensitivity and susceptibility to bacterial growth. The 16cm extended antibacterial crotch provides comprehensive hygiene protection throughout all pregnancy trimesters.

Is cotton maternity underwear better than synthetic fabric?

Cotton is generally recommended for maternity underwear because it is naturally breathable, moisture-wicking, and gentle on sensitive pregnancy skin. The 95% thin cotton fabric in these underwear provides excellent breathability and moisture management to keep you comfortable and dry throughout the day, while the high-stretch construction accommodates your growing bump.

Are these maternity underwear suitable for all pregnancy trimesters?

Yes. The V-cross construction and high-stretch 95% cotton fabric accommodate your growing bump from the first trimester through the third trimester. The low-waist design provides comfortable, non-restrictive coverage as your bump grows, and the anti-roll leg openings stay in place throughout all pregnancy stages.
